Abstract
This study is based on 2D Carreau fluid flow across a stretchable porous cylinder with thermal radiation, Soret and Dofour effects. The viscosity is supposed to be heat-dependent. The stretching phenomena is taken at the surface. The leading equations of the flow are formed into non-dimensional shape by using suitable correspondence variables. The non-linear ODEs are cracked by using BVP4C procedure with the help of Matlab software. The influence of significant parameters on mass, momentum and heat is explained numerically and graphically. The importance of porous surface is discussed numerically and graphically with the assistance of plots. The porous space has vast range of applications in the various industrial and geological areas. Porous surfaces are extensively applied in petroleum geology, solar collectors, geophysics, filtration, ventilation procedure and material science. The significant aspect of heat radiation is discussed graphically with the assistance of plots. The vital role of Soret and Dufour effects in mass and heat transport on a stretchable cylinder is presented. The reduction in fluid velocity happens for higher inputs of Weissenberg number We while increment in fluids velocity happens due to curvature parameter. The porosity and viscosity parameters express drop in the fluid velocity. The fluid heat is elevated for growing values of the heat radiation and Dufour number while plot shows decrement in Prandtl number. The source of elevation in fluid concentration is witnessed against the Soret number and curvature parameter and opposite behavior is observed with the Schmidt number. The ranges of considers variables taken areWe = 0.5, Df = 0.2, n = 0.2, Pr = 1.5, Rd = 0.1, Sr = 0.1, Sc = 1.5..
